How the YAT-205-014 model number is decoded

YAT 205-014 is SKF's 22.224999999999998 mm-bore grub-screw insert bearing with the inner ring extended on one side in the YAR2 series — a Y-bearing with a spherically ground outside surface for static self-alignment inside a matching SKF Y-housing, boundary dimensions 22.224999999999998x52x27.2 mm. Wide-inner-ring deep-groove ball geometry carries the load: the extended inner ring gives the shaft grip and the seal lands, while the outer ring stays narrow and spherically ground on its outside surface. the YAT prefix names SKF grub-screw Y-bearings: two set screws in the extended inner ring lock the shaft at a 120 deg angle, and the inner ring is extended on one side only. the three-digit -014 tail codes the bore in inches for inch-shaft bearings: 0 whole inch 14/16 in = 22.225 mm (first digit whole inches, next two sixteenths of an inch). this suffix-free execution is listed without the sealed external design: the 27.2 mm width is the one-side-extended inner ring alone, so protection depends on the housing seals and the relubrication routine rather than bearing-mounted contact seals. Envelope 22.224999999999998x52x27.2 mm (0.875x2.047x1.071 in), outer ring 15 mm wide, C 14 kN, C0 7.8 kN, Pu 0.335 kN. The catalogue publishes a single speed ceiling, the limiting speed: 7,000 r/min; mass 190 g. Fillet discipline: the printed r_min 0.6 mm limit means shaft and housing fillets must stay under that radius; a fillet that bottoms the 22.224999999999998x52 mm insert on its chamfer tilts the whole spherical seat. Pitch-diameter arithmetic: dm = (22.224999999999998+52)/2 = 37.112 mm; at the 7,000 r/min limiting speed the ball set runs at dn approx 2.60x10^5, reduced from an open bearing mainly by seal lip friction and the life-long grease fill. Capacity density: 14 kN from 0.190 kg of bearing steel is about 73.684 kN per kilogram, and per width millimetre the 27.2 mm unit carries 0.515 kN of dynamic capacity. Imperial procurement cross-check: 0.875 in bore, 2.047 in OD, 1.071 in overall width; the 190 g mass converts to 0.190 kg (6.7 oz) for the bill of materials. Inner-geometry cross-reference: the catalogue shoulder diameters (d1 33.7 mm) set the shaft-abutment and sleeve limits; an abutment larger than these numbers contacts the seal or the inner flinger. Single-extension fitting note: with the inner ring extended only on the locking side, orient the open (non-extended) face toward the shaft step or housing shoulder as the drawing shows — reversed, the set screws end up unsupported by the abutment and the shortened side offers no seal land at all. Set-screw geometry on this size: the two 120 deg screws bear on the 22.224999999999998 mm shaft inside the 27.2 mm total width while the outer ring is only 15 mm wide, leaving the extended ring to carry the screw points clear of the ball track.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• Replacement discipline: a one-side YAT insert is not interchangeable with an eccentric-collar unit of the same envelope — the shaft may need spot-facing or collar space that does not exist.
• The 19.5 mm s1 dimension is the screw seating geometry inside the 12.2 mm of extended inner ring; a shaft step that crowds that side prevents the screws reaching the shaft squarely.
• Do not specify the 22.224999999999998 mm grub-screw insert for a shaft harder than about 45 HRC without dimples: the screw points skate on hard surfaces and the unit creeps regardless of tightening torque.
• Ordering discipline for the 22.224999999999998 mm size: the chapter lists several executions side by side (YAR2 locking style x seal package x application variant); a bare-number substitution needs a fresh dimension, speed and rating check rather than a like-for-like assumption.
